We can reduce the costs of the conformal coating masking process by as much as 80%

Reduce the number of errors in processing by making the masking job much easier and reducing problems like leaking tape I thing of the past

Reduce the time for masking and de-masking by as much as 80% by simplifying the process

Don’t believe us?

We are happy to provide a free trial of our masking boots so you can test it for yourself. We can then work out your Return on Investment. All we ask is you pay for the carriage of the parts and we will refund this cost against an order if successful.

There are two realistic options for getting accurate quotes and designs made for custom boots.

These are:

Supply a sample of the PCB along with a masking diagram so that we know what needs masking.

Supply photos of the PCB along with exact dimensions of the components or the component codes . You can get this from the component supplier.

With this information we will then check against stock and quote you a price. Please remember we want to get this right so we cannot guess. We will make the boots to a very high tolerance and need to get the measurements correct.

In conformal coating many components and printed circuit board locations must remain uncoated due to the insulating nature of the coating. The purpose of the conformal coating masking materials is to prevent migration of the conformal coatings into components that need to be clear and designated keep out areas. This applies to both liquid conformal coating and Parylene processing.

Get this basic process wrong and it can be a big problem, leading to the next stage of either repairing the conformal coating leak, stripping the conformal coating off the circuit board, removing a component to replace it or scrapping the board.

Understand the fundamentals of conformal coating masking, what different materials are available, the problems associated with these masking products and how to get the best out of your process.

Want a Free Trial?

We are so confident that you will like the boots we are happy to prepare a free sample set for you to trial. We need you to provide the connector details for the board you wish to test and we will make the sample set free of charge.

All we ask is that you pay the price of the carriage as a small commitment for a big return on investment.

The number of times a masking boot, cap or plug is reusable is dependent on a number of factors including:

1. The conformal coating process
2. The complexity of the boot
3. The thickness of the wall of the boot
4. The conformal coating material used
5. How tight you require the boot to fit

The conformal coating process
If you require a tightly fitting gasket seal for processes like dipping or parylene coating you may not be able to use the boot more than 1-2 times. This is because the seal has to be perfect. But, for typical spray coating processes most boots can be reused 20-50 times. In fact, we have some boots that have never been replaced and still in use in our coating service that have probably been used over 400-500 times. They last a long time.

The complexity of the boot
The more complex the boot the more likely it will get damaged. A simple molex connector or cap box will be more durable than a three piece boot which is connected together purely down to operator handling

The thickness of the wall of the boot
All of the boots are custom made so we can vary the thickness of the walls. However, the thinner we make them the more likely they will get damaged eventually. The balance to this as that if the walls are too thick you get shadowing effects around the component and it may not fit in around tightly packed PCBs.

The conformal coating material used
Some solvents could react with the silicone boot. In reality very few do and 99% of conformal coatings are perfectly fine with the boots. But, if in doubt, check.

How tight you require the boot to fit
If you want a tight fitting boot then it makes sense that the boot will stretch with use when pulled off and pushed on. If you don’t need it tight then we can design it this way.
